Wheel Size

Bicycle wheels come in a wide range of sizes from 12" wheels found on smaller Kids Bikes to larger 29" Mountain Bike and 700c Road Bike wheels. Larger wheels are normally faster and more stable at speed and their larger contact patch improves grip too. Smaller wheels are normally lighter, more manoeuvrable and have quicker acceleration.

Wheel sizes are defined by the country that first popularised the style of bike that used them - so you'll see some imperial and some metric measurements listed. Wiggle includes the ISO standard in brackets after each for ease of comparison.

Fulcrum

There is a huge Italian tradition of cycle engineering excellence and Fulcrum was born from the very heart of it. Competition testing with world level athletes and the expertise Fulcrum's engineers possess means Fulcrum have become known for developing unsurpassed products with excellent performance, durability and market leading innovation. Key technologies pioneered by Fulcrum include 2:1 Two-to-One™ Spoke Ratio, which delivers incredible power transfer by doubling the spokes on the critical drive side of the wheels so no energy is wasted. Fulcrum has also focused on class leading rolling resistance through their CULT and USB Bearing Technologies which use ceramic bearings and cutting edge surface technology to massively reduce friction. CULT ball bearings are 9 times smoother than wheels with traditional bearings.
All this innovation and technology has produced amazing results for everyday riders and pros alike with 4 world champions in just 6 years, Boonen, Bettini (x2) and Ballan.
